Thank you. Why it needs to know how many frames are in? Usually the original defs have for most of them 1 frame, if not animated, but inserting more frames worked very well, so we could animate every building without telling how many frames are. Is it necessary or optional?

@Hero of Light: this was obvious for balance purpose. With stronghold you can have rocs day 1 and behe day 2, so now if get cyclops day 3, it will be not a town, but a killing machine.

Is there a way of removing ALL monster flags of a creature? Because If so then the 4 Gods and Santa Gremlins could be usable (those creatures suck). And If there isn't an ERM command about that, might there be a way to replace them?

For instance swordsmen have no monster flags at all (they are only alive) and so If you could find a way to copy this ability and paste it on those creatures, then you can start anew on them...
